...architecture. So one operand of ADD/SUB operations is in REG (accumulator) and the other one is in Memory. The result can be left either in REG or memory. The LLVM DAG for such operations expect both operands in REG. for example: char a, b, c, d, e; a = (b - c) + (d - e); generates addc:i8 (subc:i8(b,c), subc:i8(d,e)) Looks like we need to custom lower addc here. LegalizeOp needs modification to allow custom lowering of ADDC, etc.I will post a patch to do the same. Any suggestions on how do we custom lower such things? is using MFI::CreateFixedObject () to generate a FI and then using t...
